This may be anecdotal, but it's said that coyotes drive foxes out, and foxes are better at keeping a neighborhood clear of varmints. The years when there are foxes in our 'hood, the rabbits are much less bothersome. I only hope coyotes can do as good a job. Last year was terrible.

If you have a plague of rabbits you need a lynx to eat rabbits and keep foxes out of the area :-) nothing new under the sun.

Can you post some lynx? ;-)

Sorry, endangered. We need all of them :-)

Other than eating the occasional housecat (which is bad) Coyotes, in general, seem like good partners for our current urban/suburban life. They make hidden dens in our parks, like to eat rats and other small rodents and are scared of dogs and households. https://www.npr.org/sections/krulwich/2010/12/08/131876027/6...

I was in Chile recently, and one thing you notice is how many street dogs there are in towns/cities. They don't seem to be owned by anyone, but are fed/watered by various people/businesses and seem somewhere between domesticated and wild split into various packs.[1]

Curious how coyote and street dog packs will interact. I've heard Mexico also has a lot of street dogs, so maybe there are already first-hand accounts of what happens when a pack of coyotes moves into street dogs territory?

They will probably interbreed.

Once coyotes establish themselves, you can never get rid of them. If you try to exterminate them, they just start having larger litters until their population recovers. They are adaptable and cunning. I hope that South America’s animals are ready for them, because they can permanently change an ecosystem.

Big Felines and wolves erradicate it. Is just that we, humans are not good at that.

Big felines and wolves don't do well in urban/suburban environments. Coyotes do.

They eat chickens that people keep, kill other pets, they're basically a nuisance species in North America. Here's it's perfectly legal to shoot them year-round. And, you can cull up to 50% of the population before you would have any effect on them.

"Then, around the turn of the 20th century, nature’s barriers began to crumble. Forests began to fragment," It's impressive how wrong that statement is. 1900 is when forests stopped fragmenting, not when they started. Between 1630 and 1900 forested area of north America declined from 46 percent to 34 percent. That declined only slightly to 33 percent in 1997 and has since increased to 36.2 percent.

Yeah shortly after 1900 we got the national park movement and more state forests and wildlife reserves started getting set up. Conservation was not a thing in the 1800s. It became one in the 20th century.

Fragmenting and loss of overall area are not the same thing. A fragmented drinking cup may weigh the same as an intact one, but one of them is a lot better at holding water. A power line through a forest, for example, incurs minimal deforestation, but provides a highway for animals to transit through the surrounding forest.

I would think that power lines are a minimal impact. What probably really hurts is some species have roam areas of dozens to hundreds of square miles. With the introduction of roads and urban areas to break up some of the ecosystems that spanned multiple states, for example, had to have a much more dramatic effect. Fencing, road barriers, etc. Create choke points and make it harder especially for large predators to thrive. The Florida panther was not even an especially large feline but it did occupy a central place at the top of the food chain in Florida and now its population has been decimated due to fractured ecosystems and each one needing about 75-150 square miles of roam area.

They take small to mid size dogs too. Usually when it’s dark. Sometimes even while on a leash. Our 13 pound dog got attacked in our backyard. The coyote jumped a five foot fence with ease. The dog survived with some bite marks but the vet said usually the injuries are worse. Otherwise they cause less trouble than raccoons who get into a lot of things.

If you want your cat to participate in nature, to have the opportunity to kill wild animals, you have to accept the possibility that other wild animals might try to eat your cat. Wanting the former but not the latter, wanting to have your cake and eating it too, is unreasonable.
